User/LisaL

This page describe how to use Lisa/L from a user point of view

Getting started

• Install Gnu/Linux Ubuntu lucid lynx ( 10.04) and the paparazzi-dev and paparazzi-stm32 packages ( Installation from the Command Line: om this page Installation ).

sudo apt-get update
sudo apt-get install paparazzi-dev  paparazzi-stm32

• Connect power to the board. The board accepts input voltage from 6V to 18V. The power connector is from JST and known in the rc world as a BEC connector
• Connect a mini USB cable in the mini USB connector. This should give you two USB devices. The first one ( usualy /dev/ttyUSB0) is the console for the Overo, the second one is the JTAG for the STM32
• Flash a test program in the stm32 :

 make AIRCRAFT=BOOZ2_A7 test_baro.upload

Overo

• The main documentation page for the overo on gumstix website is here.
• We now have a Overo toolchain package ! install the paparazzi-omap package. If you feel it's too easy, you can look at here and enjoy the fun of compiling openembedded yourself
• In order to use the SPI link between the STM32 and the Overo, you'll need a patched linux kernel and a couple of libraries. Look in the developer section if you wanna know the gore details of it. If not, just download our pre-compiled filesystem image and kernel from here and follow the instruction from here to write them on a micro sd card.
• Flash the STM32 with the link test program

 make AIRCRAFT=BOOZ2_A8 stm_test_spi_link.upload

• Compile and upload the Overo test program ( assuming you already have the overo toolchain and network... mmmm... more about that soon...)

 make AIRCRAFT=BOOZ2_A6 overo_test_spi_link.upload

• Log on your Overo and run it

Use case #1: the fixedwing firmware running in the STM32 only

Coming soon... look for airframes/AirborneCodeReorg/LisaFw.xml

Use case #2: the rotorcraft firmware running in the STM32 only

Use the airframes/Poine/booz2_a7 as an example. You may only have to change some subsystems type to match your peripherals.

   make AIRCRAFT=BOOZ2_A7 ap.upload

Use case #3: the lisa_passthrough firmware

This firmware turns the STM32 into a simple io processor that sends sensors and radio control to the Overo and fetches actuators position in return.

The overo_test_passthrough target demonstrates the use of the Paparazzi framework on the Overo: communications with the stm32, accurate periodic events and telemetry/datalink over anetwork link like wifi.
